Google is selling its Mobility unit to Lenovo for $2.91 billion, according to an official blog post by the search and mobile OS giant. Check on this article from PCWorld.com.

The Mobility unit includes handsets and patents associated with Motorola Mobility, which Google bought for $12.5 billion back in 2011. Google sold the Motorola Home division shortly after the initial acquisition, and though the Motorola Moto X was one of our favorite phones last year, its sales numbers haven’t exactly shot through the roof.

Lenovo, on the other hand, is already the world’s top PC manufacturer and has been ramping up its mobile efforts. In fact, it already sells more mobile devices than proper PCs, largely in Asian countries and particularly in China.

According to Google, the move will:

enable Google to devote our energy to driving innovation across the Android ecosystem, for the benefit of smartphone users everywhere. As a side note, this does not signal a larger shift for our other hardware efforts. The dynamics and maturity of the wearable and home markets, for example, are very different from that of the mobile industry. We’re excited by the opportunities to build amazing new products for users within these emerging ecosystems.

Carolina Milanesi, a consumer trends analyst, posits that the sale to Lenovo could have something to do with the Samsung and Google patent deal, which makes the rumors of Samsung’s makeover of its gaudy TouchWiz UI that much more interesting.

The recent acquisition of Nest and Boston Dynamics would suggest that Google isn’t totally steering toward a software-only venture—just that it’s putting the physical Android phones into someone else’s hands. We’ve reached out to Google for a comment.
